Calendar
A very disturbing calendar showed up in my calendar on my iPhone. How did it get there? Is my phone or info on it compromised?
Question marked as
Somewhere along the way, you got a “do you want to get alerts” message and chose to accept a calendar.
This is common. There’s no compromise, no virus, no malware, just a shared calendar that you now don’t want.
